Update on Algorithms for Carmichael numbers
In this note, we present progress on determining the computational complexity of tabulating all Carmichael numbers less than some bound $B$. We implemented a new tabulation algorithm which we describe here. In lieu of providing an asymptotic analysis of that algorithm, we show a second related algorithm that we claim is optimal under two believable conjectures.

Since I've left my last job, I've been thinking about the guy who used me as an alternative to ChatGPT whenever he hit a problem that he couldn't vibe code the answer out of at work. He basically rotted his own brain by compulsively using ChatGPT in lieu of actually thinking with most any of the projects he was working on. Instead of taking the time to read through code in our framework, look up documentation, or do any sort of debugging, he instead just begged and pleaded with ChatGPT to try …

That fractal that's been up on my wall for 12 years
Warning: Math, Handwaving I spent a lot of time doodling in middle school in lieu of whatever it is middle schoolers are supposed to be doing. Somewhere between the Cool S’s and Penrose triangles I stumbled upon a neat way to fill up graph paper by repeatedly combining and copying squares. I suspected there was more to the doodle but wasn’t quite sure how to analyze it. Deciding to delegate to a future version of me that knows more math, I put it up on the wall behind my desk where it has …

Q Hayashida est le pseudonyme d’une mystérieuse autrice de mangas japonaise, qui protège ardemment sa vie privée. D’après la page Wikipédia qui lui est consacrée, on sait très peu de choses d’elle. Outre sa date et son lieu de naissance (1977 Š Tokyo), on peut y lire qu’elle a étudié Š l’Université des arts de Tokyo...

L'agacement du jour : "l'agent en ressenti déceptif". Enfin, je cite celui-ci, mais je suis en ressenti répulsif sur une ribambelle d'autres, l'auteur en charge des pages en cours de correction ayant opté pour l'adoption répétée, récurrente, constante et durable d'un style relevant du jargon technique et spécifique en congruence… ou pas (pour une bien pâle imitation).
Éclatons de rire au lieu de nous arracher les cheveux…
